TOY AEROPLANE.

Specification of Letters Patent.

Application flled- July 6, 1911.

Serial No. 637,073.

To all whom it may concern:

Be itknown that we, Gus M. KAISER and; ALFRED S. Hncrrr, both citizens of the United States, and residents of the city of New York, borough of Manhattan, in the county andState of New York, have invented a new and Impro'ved Toy'Aeroplane, of which the following is a full,-clear, and exact description.

Our invention relates to toy aeroplanes, and it has for-its objectto provide one which may be constructed at trifling expense, so that the aeroplanes may be manufactured in quantities and may be given away for advertising purposes or be sold for a few cents.

We prefer to construct the principal parts of the aeroplane of cardboard, the propeller and the body being each constructed of a single piece of cardboard, the cardboard being scored and folded to the desired shape, after which the parts are pasted together.

Other objects of the invention will appear in the following specification, in which the preferred form of our invention is described.

Similar reference characters refer to similar parts in the several views of the draw ings, in' which- Figure 1 is a perspective view of the aero-. plane; Fig. 2 is a plan view of Fig. 1; Fig. 3 is a plan View showing the blank from which the body of the aeroplane is constructed; Fig. 4 is a plan view of the blank from which the propeller is constructed; Fig. 5 is a rear end view of the blank shown in Fig. 3,, partially folded; Fig. 6 is a-front end view of the blank shown in Fig. 3, partially folded, and Fig. 7 is a side elevation of the front of the aeroplane.

Byreferring to the drawings it will be seen that a blank 10 is provided, the sides 11 and 12 of which converge to the right. This blank 10 is scored longitudinally at 13, 14 and 15, to form a reinforcing member 16, a bottom member 17 and sides 18 and 19. At the rear end 20 of the reinforcin member 16 there are two flaps 2l wh1ch are spaced from each other and which are curved at their inner sides 22. The inner reinforcing member 16 does not extend as far rearwardly as the.body of the blank 10. At the rear of the sides 18 and 1 9 there are flaps 23 and 24, and at the rear of the bottom member 17 there is a flap 25, the flap 25 extending beyond the rear of the flaps 3 and 24 and being scored at 26, so that it member 16 does not extend as far forward as the side members 18 and 19 and the bottom member 17, the sides 18 and 19 being curved outwardly at 27 and 28, as indicated in Fig. 3 of the drawings' There is also a flap. 29, which is a part of the blank 10 and which projects in front of the side member 18. Near the rear of the blank 10 and extending from the side member 19, there is a lateral projection 30, from which is formed the keel member 31. The lateral projecting member 30 is scored at 32 and again at 33, and flaps 34 are formed by cuts 35. v

The blank 10, after it has been stamped out and has been scored as indicated, is folded as follows: The side members 18 and 19 are bent upwardly relatively to the bottom member 17, the inner reinforcin memlatcnted Aug. 6, 1912.

her 16 is bent within the side members 18 and 19 and the flaps 21 are folded face to face and glued together. The inner reinforcing member 16 is also glued to the bottom member 17 and the inner faces of the side members 18 and 19. The flap 29 is then tent around the front and against the inside of the side member 19 and glued to inclose' the body of the aeroplane at the how. The flaps 23 and 24 are folded on score 36, one 1n front of the other and are glued together, and the flap 25 is folded at the score i 26 and then is folded at the score 36, so that four surfaces of the cardboard will lie face to face at the rear of the body of the aeroplane. The lateral projecting member 30 is bent at the score 37, as shown in Fig. 5 of the drawings, and then it is bent again at the score 32,.so that that part between scores 30 and 32 will beagainst the side member 19 and the remainder of the lateral projecting member 30 between scores 32 and 33 will be disposed against the underside of bottom member 17. The keel member 31 is then Q bentat the score 33, so that it will be disposed downward, and the flaps 34 are also bent atthe score 33, so that they will lie against the bottom of the body of the aeroplane opposite that portion of the lateral projecting member 30 which is disposed be tween the score 32 and 33. When the lateral projectin member 30 and the flaps 34 are glued to t e side member 19 and to the body of the aeroplane and also through ori-f bottom of the member of thefaeroplane, it will be found that the keel. membe 31 will be heldfirmly in position.

- The propeller 38 is stamped out of the 38, andthe free terminal 44 of this wire is inserted in "orifices 45 in the rear of the fices'which are made in the flaps 21. An elastic 46 is then secured to the free terminal 44 of the Wire, forward of the flaps 21, and

this elastic is secured at the forward end of the body of the aeroplane to a hook 47, which in turn is secured to the bottom'niember 17; A bead- 48 is mounted on the wire 43 at the rear of the body of the aeroplane, to reducefriction, a twist being made in the wire 43 in the rear of the head 48, to limit the forward movement of the propeller 38.

Two plane members 50 and, 51 are provided, the plane member 51being preferably smaller than the planemember 50. The plane member 50 is mounted on the body member 52 of the aeroplane and is disposed near the rear of the body and above the keel member 31. An elastic band 53 is then disposed under and'across the body member 52, over and across the plane member 50, and again under the body and at the rear of the keel member 31, to hold the plane 50 yieldingly in position. The other plane 50 is mounted on the body 52 .atthe bow 54, the curves 27 and 28 in the sides 18 and 19 a J causing the body member 52 at the bow to curve upward and forward, so that when the plane 51 is moved forwardly, its for-.-

warcl edge will be raised slightly relatively to itsrear edge. By moving the plane 51 forward or rearward at the bow o'f'the body 52, the direction as to elevation in which the aeroplane will'be driven will be regulated.

The plane 51 is secured in the same manner as the plane 53 bya rubber band. 55.

Having thus described our invention, we' claim asnew and desire to secure by Letters Patent:

1. In an aeroplane, a piece of cardboard scored to form a bottom, sides and an inner in r aaeater o t t a the cardboard" being bent at an angle to the bottom of the reinforcing member, said rein-j forcing member being secured" betweenthe sides.

scored to, form a bottom, sides and. a reinforcing member having two flaps at one end, the sides of'the cardboard being bent rel- 2. In an aeroplane, a piece of cardboard atively to the bottom and the reinforcing member being-secured between the sides with the flaps secured faceto face.

- 3. In an aeroplane, a piece of cardboard scored to form-a bottom, sides and an. inner reinforcing member of a body, the piece of cardboard having flaps at one end, the sides of the cardboard being bent relatively tothe bottom, the reinforcing member being-secured between the sides and the flaps being secured face to face.

4. In an aeroplane, a piece .of cardboard, I

the sides of which converge in one direction,

the cardboard being scored to form a bottom, sides and an inner reinforcing member of a tapering body, the sides of the cardboard being bent relatively to the bottom and the reinforcing member being secured between the sides.

5. In an aeroplane, a pieceof cardboard.

scored to form a bottom and sides of a body having a lateral extension for forming a keel, the sides being bent relatively to the bottom and the lateral extensions being bent under the bottom, and means for securing the partsin place.

6. In an aeroplane, a plece of cardboard scored to form a bottom, sides and an inner reinforcing member having a flap with an orifice, there being a second flap with an orifice at one end of the piece of'cardboard, the cardboard being bent, with the second flap secured across the end of the device and 'the'reinforcing member secured betwen the sides, with the first-mentioned flap spaced from the second-mentioned flap and secured across from one side to the other, a stud disposed in the orifices and projecting from the device, a propeller secured to the stud be yond the device, and meansfor.rotating the stud.
